Grams 72mm Throttle Body - FRS/BRZ/86
Grams Performance 72mm Drive-By-Wire Throttle Body. This is a high-performance direct bolt-on upgrade over the factory restrictive throttle body. The Grams Performance unit does not require swapping electric motors, wiring, or mounting adapters, and each unit is not re-manufactured. Each throttle body includes all new components including a CNC machined billet 6061-T6 aluminum housing with a precision-honed oversized bore, a responsive high-torque servo motor, and a proprietary Non-Contact Hall Effect TPS Sensor.
